big endian.

* TODO Rigid endian :LIB:
Say a program is compiled on a little endian machine. The resultant
bytecode file, as a result of using C's internal functions, will use
little endian.
This file, when distributed to other computers, will not work on those
that use big endian.
This is a massive problem; I would like bytecode compiled on one
computer to work on any other one. Therefore we have to enforce big
endian. This refactor is limited to only LIB as a result of only the
~convert_*~ functions being used in the runtime to convert between
byte buffers (usually read from the bytecode file directly or from
memory to use in the stack).
2024-04-09: Found the ~hto_e~ functions under =endian.h= that provide
both way host to specific endian conversion of shorts, half words and
words. This will make it super simple to just convert.
* TODO Preprocessing directives :ASM:
Like in FASM or NASM where we can give certain helpful instructions to
the assembler. I'd use the ~%~ symbol to designate preprocessor
